Pushing the limits of perfection

Jesse Sherman M

Loving my new Supra! The SL 450 performs incredibly, and produces the best waves on the lake! Smooth, powerful, and able to accommodate a lot of passengers and gear. Everything about the boat is top notch. I wouldn't trade it for any other make of boat, period. Well done, Skiers Choice!

Great boat, great dealership, great fun

The Grey Goose!

Danielle F

Our Supra 2021 SL400 that we've dubbed "The Grey Goose" for it's all light graphite hull with black accents is hands down the best boat we've ever owned. The fit and finish, intuitiveness, level of technology, surf system adaptability and comfort are second to none. We are very happy we decided to go with the Supra over the other manufacturer's that we looked at.

Great Boat!!

Consistent Customized Wakes

Norman H

We now have 125 hours on our 2019 SL450 and cannot be more satisfied with the reliability, the great style and luxury of the boat, but most of all with the consistency in shaping wakes for both surf and wakeboard riders. Whether it is a crew of 3 or 12, a full tank of gas or empty we can adjust and save our settings for a perfect wake for each rider. The economy is great too, with the engine purring at relatively low revs for both regular and goofy setups when fully loaded.

ORR Marine Supra SL450

Kyle H

I’ve owned a 2017 Moomba Craz Surf Edition and now a 2021 Supra SL450 and both boats have provided my family with a lifetime of fun memories. Both boats have met and exceeded my expectations on bringing my kids along with their friends around their “uncool” parents almost every weekend of the summer. Whereas before my children were off every weekend to their friends boating excursions. For the last 4 summers I’ve had my kids, plus some, back hanging with the me all weekend. #cooldad #memories

Great Surf Boat!

Del C

I am extremely satisfied with the quality of the wave the boat produces for surfing!

Matt B

I can’t tell you how impressed we are with this boat. Nick at Romoboco was great to deal with. He allowed us to use his build slot to pick exactly the colors and options we wanted. We mainly surf and everyone can agree that we have all improved significantly mainly because the boat throws a great wave. 50 hrs on it now in 4 weeks!

Love this boat!


I love my boat! This Supra SL450 is a great boat, and provides the surfing and wakeboarding wake that I required!

Purchase of the Perfect boat, and experince

Charles M

The team at the Slalom shop has provided the perfect experience to purchasing a boat. I purchased a 2020 sl 450 from Jeremy Lear at the Slalom Shop and plan for the years to come to remain a Supra owner! Keep up the good work, I only see great things in the future with this boat brand! Two months and 80+ hours on the boat, I would say this has been the perfect boat for my family!

It’s Supra or Nothing

Jason S

If you’re in Utah MARIND PRODUCTS is the absolute authority on all things Supra, it’s my second Supra I’ve owned and the SL runs like a dream!

Great customer service and knowledge of their products

Phillip B

The salesman have great knowledge of the boats and are willing to meet you on the water and give you a demo of how your boat works. The showroom at boat country is beautiful when it’s loaded with boats. I would recommend this place if your looking for a boat.

Surf like a pro!

Car Pros L

Our family has surfed on all the competitors and we will continue to purchase Supra boats.

Super Super Supra

Robert T

Just purchased new Supra. Loved the technology on the boat. Youngest daughter easily was able to surf a wake. Family/friends easily towed with a 4 person tube. Previously owned a Tige. This boat is superior for less money in my opinion.

If you want great quality control and build of your boat, and a no hassle wave (no tweaking settings) right out of the box. Supra is your answer

I love my Supra and my Boat dealership even more!

Patrick P

Performance Marina in Osage Beach, MO is one of the best buying experiences I have had. Ive been in Sales 29 years and Joe Norton and Jeff Sartain sell but walk you thru the boat purchasing process. They help yo make the right decision for your family. I have the Supra SL 450 and it is awesome! Surfing unreal, cruising satisfaction off the charts!

Supra SL 450

Kevin P

After a year of ownership, I feel the Supra SL is the "Perfect Boat". Supra's build quality and features rival or exceed other manufacturers at higher price points. This is the first time in my life I haven't had "boat envy" for other boats I see out on the lake. I just feel sorry for those who paid too much for an inferior product.
